What is the Difference Between Saltatory and Continuous Conduction?

Saltatory and continuous conduction are two methods of signal transmission along nerves. The main differences between them are:

1. Occurrence: Saltatory conduction occurs via myelinated axons, while continuous conduction occurs along the entire length of unmyelinated axons.
2. Speed: Saltatory conduction is faster than continuous conduction. The action potential skips from one node of Ranvier to the next in myelinated axons, speeding up the arrival of the impulse at the nerve terminal. In contrast, continuous conduction is slower because the action potential is generated along the entire length of the unmyelinated axon.
3. Energy Efficiency: Saltatory conduction is less energy-consuming than continuous conduction. Continuous conduction utilizes more energy and delays nerve impulses due to the higher number of ion channels required to generate an action potential.
4. Action Potential Generation: In saltatory conduction, the action potential is only generated at the nodes of Ranvier in myelinated axons. In continuous conduction, the action potential is generated along the entire length of the unmyelinated axon.

In summary, saltatory conduction is a faster and more energy-efficient method of signal transmission compared to continuous conduction. Saltatory conduction occurs in myelinated axons, while continuous conduction takes place in unmyelinated axons.

Comparative Table: Saltatory vs Continuous Conduction

Saltatory and continuous conduction are two types of nerve impulse transmission in neurons. The main differences between them are:

Saltatory conduction is faster because the action potential jumps from one node of Ranvier to the next, and the new influx of sodium ions renews the depolarized membrane. In contrast, continuous conduction is slower because there are always voltage-gated sodium channels opening, and more sodium ions are rushing into the cell.
